In this respect, for the textile device according to the invention, temperature metering independent of changing ambient conditions is made possible.
- According to a first preferred embodiment of the textile device according to the invention, provision is made for the main structure to be equipped both with a sensor thread for sensing a temperature of the main structure and with a sensor thread for sensing a dampness of the main structure.
- Here, the at least one heating thread and the at least one sensor thread may be attached in the region of the same top or bottom surface of the main structure, or the at least one heating thread may be attached in the region of the top surface of the main structure and the at least one sensor thread may be attached in the region of the bottom surface of the main structure.
- According to an important preferred embodiment of the textile device according to the invention, the control circuit is configured to control the intensity of a current flow through the heating threads in response to a measured temperature or dampness in order, for every measured actual value, to introduce into the main structure a predetermined setpoint value of heat in order to bring the main structure to an always identical predetermined temperature.

In this way, easy coupling to a voltage source, which has generally adjacently arranged electrical terminals, is ensured.
- Furthermore, the loop of the heating thread may be introduced into the main structure so as to run in meandering fashion such that a first loop part, which leads from the first end of the heating thread to a reversal point of the heating thread, is laid parallel, with a predefined spacing, with respect to a second loop part, which leads from the reversal point to the second end of the heating thread.

Claims (15)
1. A textile device (100) having a flexible textile main structure (110) which is made up of textile threads (101) and which has a top surface (111) and a bottom surface (112), wherein:
the main structure (110) is equipped with at least one electrically conductive heating thread (120) which is connected to a first voltage source and with at least one electrically conductive sensor thread (130) which is connected to a second voltage source and which serves for sensing a temperature or a dampness of the main structure (110); and
a control circuit which is electrically connected to the at least one sensor thread (130) is provided for controlling the intensity of a current flow through the at least one heating thread (120) in response to a measured temperature or dampness in order, for every measured actual value, to introduce a predetermined setpoint value of heat into the main structure.
2. The textile device (100) of claim 1 , wherein the main structure (110) is equipped both with a sensor thread (130) for sensing a temperature of the main structure (110) and with a sensor thread (130) for sensing a dampness of the main structure (110).
3. The textile device (100) of claim 1 , wherein the at least one heating thread (120) and the at least one sensor thread (130) are attached in the region of the same top (111) or bottom surface (112) of the main structure (110).
4. The textile device (100) of claim 1 , wherein the at least one heating thread (120) is attached in the region of the top surface (111) of the main structure (110) and the at least one sensor thread (130) is attached in the region of the bottom surface (112) of the main structure (110).
5. The textile device (100) of claim 1 , wherein the control circuit is configured to control the intensity of a current flow through the at least one heating thread (120) in response to a measured temperature or dampness in order, for every measured actual value, to introduce into the main structure (110) a predetermined setpoint value of heat in order to bring the main structure (110) to an always identical predetermined temperature.
